The Kit
There are quite a few parts that are needed to build all the projects in this book. The
first time I taught this class, I assembled kits which were sold through the bookstore
for $100 each. One kit was required for each lab group of two people. Many of the
parts were acquired from surplus stores, so your pricing may be significantly different depending upon your supplier. In addition to the kits, selections of resistors and
capacitors were made available in the lab. Since this was a project oriented class, I
wanted to give my students the tools to do much of the work outside of lab.
A parts list for a reasonable kit is shown below.

Other Supplies
In addition to the kit, there are some other supplies that will be need to accomplish
the projects. However, these can easily be shared among multiple groups. These
include some construction materials for building the intersection (a hot glue gun,
cardboard, construction paper, etc.) and the Smart Shower setups. I also kept a few
extra kits in reserve to replace broken parts.
The Smart Shower
The Smart Shower apparatus is shown below. Hot and Cold water tanks are emptied
via two automobile windshield wiper pumps (available at most auto supply stores).
These flow into a mixing chamber with a small hole in the bottom. There is also a
float switch in the mixing chamber to allow detection of the desired fluid level.
Underneath the Mixing Chamber is a Collection Tank which receives the “shower”.
A high current automotive type power supply is available which is sufficient to
drive both pumps simultaneously. A nice touch is to bring all electrical connections

ture sensor into the mixing chamber. We found hot glue provided an adequate water
tight seal of the electrical connections.
Test Equipment
Some basic test equipment is required to complete the projects. This includes a
multimeter and an oscilloscope, which are generally available in undergraduate
electronics labs. If it can be afforded, it would be an excellent idea to include an
inexpensive DMM in the kit.
